EHEIM EHFI Drafin 0.7L

The Eheim EHFI Drafin filter medium is designed for mechanical pre-filtration of water in your aquarium. It effectively traps coarse debris, preventing it from entering other parts of the filter. This protects the subsequent layers of biological and fine filter media from clogging up too quickly and extends their service life. The pack contains 0.7L of media, which should be placed as the first filter layer.
